This study investigates the flotation beneficiation of ultrafine magnesite rich in dolomite from de-sliming, currently reported to the tailings. The paper especially focuses on the impact of the depressant sodium hexametaphosphate (SHMP) on: (i) the froth properties using dynamic froth analysis (DFA), (ii) the separation between magnesite and dolomite/calcite and (iii) its effect on the entrainment

Oct 15, 2020 · The micro-flotation of dolomite and magnesite was carried out in a laboratory flotation device (mechanical agitation) with a 30-mL detachable cell and a stirring speed of 1992 rpm. The flotation slurry was prepared by adding a single mineral (2 g) or artificially mixed minerals (1.2 g magnesite and 0.8 g dolomite) into 25-mL DI water in the flotation cell
